4.2.1

Power Dissipation

During operation, the temperature of the die should not exceed the operating junction temperature noted in Table 4. To optimize

the thermal management and to avoid overheating, the PF0200Z provides thermal protection. An internal comparator monitors

the die temperature. Interrupts THERM110I, THERM120I, THERM125I, and THERM130I will be generated when the respective

thresholds specified in Table 5 are crossed in either direction. The temperature range can be determined by reading the

THERMxxxS bits in register INTSENSE0.

In the event of excessive power dissipation, thermal protection circuitry will shut down the PF0200Z. This thermal protection will

act above the thermal protection threshold listed in Table 5. To avoid any unwanted power downs resulting from internal noise,

the protection is debounced for 8.0 ms. This protection should be considered as a fail-safe mechanism and therefore the system

should be configured such that this protection is not tripped under normal conditions.
